L293D is a monolithic integrated, high voltage, high current, 4-channel driver.
you can use DC motors and power supplies of up to 36V.
the L293D chip is also known as a type of H-Bridge, which typically is an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. motor.
2 interface for 5V Servo connected to the Arduino's high-resolution dedicated timer - no jitter.
Can drive 4 DC motors or 2 stepper motors or 2 Servo.
Up to 4 bi-directional DC motors with individual 8-bit speed selection.
Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.
4 H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can drive motors from 4.5V to 36V DC.
Pull down resistors keep motors disabled during power-up.
2 external terminal power interface, for seperate logic/motor supplies.
Tested compatible for Arduino Mega, Diecimila & Duemilanove.
1x L293D Motor Drive Shield for Arduino Mega 2560 / Uno
